Step-by-step explanation:
5x - 2y
5(-2) - 2(-2)
-10 + 4
= - 6
The value of ? and X are 12 and 24 respectively
<h3>Similarity theorem of a triangle</h3>
A triangles is 2D shape with three sides and angles.
From the given diagram, the ratio of similar sides is equal to a constant as shown;
15/20 = 9+15/20+x
Cross multiply
15/9+15 = 20/20+x
15/24 = 20/20+x
Comparing with the given ratio
? = 24
X = 20+x
Find x
15(20+x) = 480
300 + 15x = 480
15x = 180
x =12
Fro the given expression
x/32 = 9/?
12/32 = 9/?
12 ? = 32 * 9
? = 24
Hence the value of ?and x from the given diagram is 12 and 24 respectively

Step-by-step explanation:
a. the domain ={-3, 0, 1, 2}
the range = {6, 2, 0, -3}
the relation is a function
b. the domain = {-1, 2, 1}
the range = { -4, 8, 4}
the relation is not a function
